Still working out that part. But I do know that there are systems where you can create a multiclass character. For example you could start off as a Champion(Which is a warrior type class) but then for your second level you could choose a second class and be a Champion Bard. (Essentially have the abilities of both a lvl 1 Bard and a lvl 1 Champion)

As for Alignment, if you can explain why the change would occur and the DM is fine with it then it is perfectly acceptable with the rules.
